ACE Virtual Environment Protection 2 — Questions and Answers
Question 1: Which Acronis feature allows you to run a backup of a VMware VM directly from the ESXi host without installing an agent inside the guest OS?
- Agent-based backup
- Agentless backup via vSphere API (Correct answer)
- Bare-metal restore
- CBT-only backup
Correct answer: Agentless backup via vSphere API
Acronis leverages VMware's vSphere API for Data Protection (VADP) to perform agentless backups at the hypervisor level without a guest agent.
Question 2: What is the purpose of Changed Block Tracking (CBT) in VMware VM backups with Acronis?
- Encrypts backup data in transit
- Tracks only the disk blocks that changed since the last backup to speed up incrementals (Correct answer)
- Compresses VM snapshots automatically
- Monitors VM network traffic
Correct answer: Tracks only the disk blocks that changed since the last backup to speed up incrementals
CBT records which disk blocks have changed since the previous backup, enabling Acronis to back up only modified blocks during incremental jobs.
Question 3: When protecting a Hyper-V VM with Acronis, which component must be installed on the Hyper-V host to enable agentless VM backup?
- Acronis Agent for VMware
- Acronis Agent for Hyper-V (Correct answer)
- Acronis Backup Gateway
- Acronis Agent for Windows inside each guest
Correct answer: Acronis Agent for Hyper-V
Acronis Agent for Hyper-V is installed on the Hyper-V host and uses VSS to take consistent snapshots of VMs without requiring in-guest agents.
Question 4: A VMware backup fails with 'snapshot consolidation error.' What is the most likely root cause?
- Acronis quota exceeded on the backup storage
- Residual snapshot files left from a previous failed backup causing delta disk chain issues (Correct answer)
- The VM has no network adapter configured
- CBT is not supported on this version of ESXi
Correct answer: Residual snapshot files left from a previous failed backup causing delta disk chain issues
Leftover delta VMDK files from a prior failed snapshot cause consolidation errors when Acronis attempts to take a new snapshot.
Question 5: Which Acronis recovery option lets you instantly start a backed-up VMware VM directly from Acronis backup storage without fully restoring its VMDK files first?
- Instant VM Recovery (Run VM from Backup) (Correct answer)
- Cross-hypervisor migration
- Bare-metal restore to ESXi
- P2V conversion
Correct answer: Instant VM Recovery (Run VM from Backup)
Acronis Instant VM Recovery mounts the backup as a datastore and boots the VM directly from backup storage, minimizing downtime.
Question 6: In Acronis, what does 'application-consistent backup' mean in the context of a VM running Microsoft SQL Server?
- The backup is taken while the SQL service is stopped
- VSS is used to quiesce SQL Server and flush in-flight transactions before the snapshot (Correct answer)
- The VM disk is encrypted before backup
- SQL data files are excluded from the backup
Correct answer: VSS is used to quiesce SQL Server and flush in-flight transactions before the snapshot
Application-consistent backups use VSS to quiesce the application so all in-memory transactions are flushed to disk, producing a recoverable backup state.
Question 7: Which network component in Acronis Cyber Protect acts as the transport layer for moving VM backup data from an ESXi host to remote cloud or tape storage?
- Acronis Management Server
- Acronis Backup Gateway
- Acronis Storage Node
- Acronis Agent for VMware (Virtual Appliance) (Correct answer)
Correct answer: Acronis Agent for VMware (Virtual Appliance)
The Acronis Agent for VMware deployed as a Virtual Appliance (VA) on the ESXi host handles data transport from the host to backup destinations.
